Application filed October 25, 1920. Serial No. 419,354.

To all whom t concern.:

Be it known that I, JOSEPHHEOKENBACH,

a citizen of the United States, and a resident by which means isprovided for preventing' accidental unscrewing of the cup from position,and by which an .improved operation isattained. v

Other objects will appearhereinafter. The invention consists in thecombinations and arrangements of parts hereinafter de'- scribed andclaimed. j

The invention will be-best understoodby reference to the accompanyingdrawingsforminga part of this specification, and in which,'.fv

Figure l is substantially a central vertical section through myimproved' device;

Fig. 2 is a vertical. section taken at line Fig. 3 is a horizontalsection taken at line,

3 3 of Fig. 1.

Figa is a horizontal vsection taken at' line forcentering and aliningthe members with` respect to each" otherby reason of the point ofengagement 'between suchy tubes ,b'eing atv some littlefdistance outsideof the plane.

Fig.- 5 is a vertical section similar to Fig. 1 but showing achangednfposition oi the parts; and

F1g.6 issubstantially a; central vertical section through a modifiedform of device.

. Referring to Figs. V lfto j5 inclusive, l0

indicates a stud provided with'screw threads at its lower endfor-screwing it in position with respectl to'a bearing, and being pro--vided with screw'threadsat itsupper-end for securing acup thereon; 11'indicates a' cup provided?,v with screw Athreads adapted to it upon thestud 10 as iscommon Vpractice in the; manufacture of devices of thistype. As

is fully underst ood,'in practice the cup. 11 is to be'illed with-asupplyj of lubricating material and to bescrewed into position on thestud, thecupbeing loweredwith respect. to the studfromtime to'time for'forcijngthe.

grease frolnthe cupV downwardly through a central opening ini. the.sind. Fgfli .shews the cup 11 in position'lfor effecting engagementibetween the threads oftheA cup and J[he threads of the stud, while Fig.5 shows with fthe grease VeX-vy the partsl in position hausted from thecup. l

Means is .provided for:v alini'ng the cup and the stud with respect ltoeach other for effecting aproper engagement between the threadsolf-these members,

ment is about to Vtakje place.y 'This-means in the construction showncomprises-a tube'12 securedin central position with`respect to the vstud1 0, being adapted to extend intok a QUALITY HARDWARE a' n g beingadapted to. be operative at .the'tnn'e when such engage-V second tube 13carried by the cup lllinconLV l Y centric pojsitionfftherein.- Asisbest-shown in Fig. 1, the tubeV 12 -isprovided w'ithf'al pluralityofspring lingers 14' so positioned uponthe tube 12 as to'engagetheend 'ofthetube 13'at'the 'time when the threads of the stud lOare about toengage 'the/threads ofthe cupV 1-1. `In 'the construction shown three oftheV fingers 14 are provided,l spaced evenly about the periphery of lthetube 12, whereby the cup 11 is supported by :such spring fingers inalinement with the 'stud' 10.

The tube 12 has a tendency to center the stud andthe cup with respect to`each other by reason of -its snug engagement withthe tube 13lindependentlyV of the action of the-- spring fngers'14. f Theengagement between the tubes12 and113 is particularly effective lingerslet are cutout from thl'elwallioffthe tube l2 being bent intothe desiredormso as to stand normally inslightly projecting position'with respectto th'e tube-as shown in that figure. 'I have `found that fingers cutoutinfthi's manner fromthe stockfofa commercial tube havetherequlredamount 7ol Y of resiliency without any specialtreatment.

Asis clearly shown .1in-Figs. and 4, the tube 13i s angular-1n crosssect1on,' being of hexagonal form :in the construction shown. As-willb'ereadily understood, when the-cup 11 is screwed into position'uponthestud 1 0, .the fingers 14am forced'weldly e@ to enter the tubel.When the cupY 11 vis turned so as to cause the fingers-lato standopposite the angles of the tube 13, the ingers are permitted to projectvery slightly outwardly, engagement with the tube. The iingers .14accordingly offer 'a slight yielding resiste.

ance to rotary movement of the cup 1-1 w ith respect to the stud 10,this resistance being sufiiciently effective to' prevent accidental nunscrewing of the cup 11 from the stud10.

I wil'l'be readily lunderstood* without further The cup 11 is providedat its' upper end with `an extension 15' vcfre'duced size within'Y whichthe tube 13 is secured, the extension being 'oia vertical length foraccommodat ing the, tube 12 as is shown'in Fig. 5. As the cup 11 isilowered with respect tothe stud 10, the grease romthe cupl'is forcedVthrough the tube-12, being adapted to enter the tube 12 .throughopenings 'about the'liingers 14, and through openings! 16 inthe 11without any material portion of the grease being left in the Vcup toharden and prevent proper flow of the greasev atitsnext application'.

In Fig. 6, a modified or-mof construction' is', shown Vcomprising a stud17 having a socket 18 of hexagonal shapeI corresponding tothe socketprovided by the tube 13 oit the first described construction. A tubecor;Y

responding? to' the tube 12is mounted iirthe cup'A 11 in lieu of beingmounted upon thev stud. Spring fingers QOcutrom thewall of thet'ube 19are' adapted toengage the-angles of thef socket 18 for effecting similarresults AV slot 21 is pr'rovidedl'in theupper end 'ofthetub'e 19 foradmittinggreasefrom the cup to the interior of ther tube 19, coivresponding to the function' of' the opening' 16 in the'tube 13".
